To: linux-mips@linux-mips.org, ralf@linux-mips.org
Subject: PATCH: Fix mc146818_decode_year
From: tsbogend@alpha.franken.de (Thomas Bogendoerfer)
Date: Sat, 3 Feb 2007 14:06:10 +0100
Original-recipient: rfc822;linux-mips@linux-mips.org
Sender: linux-mips-bounce@linux-mips.org
User-agent: Mutt/1.5.9i
Big endian RMs uses a different mc146818_decode_year than little endian RMs
Correct mc146818_decode_year for years before 2000
